BRA'IDING- SPEClFKCATION forming part of Letters Patent No. 717,415,dated December 30, 1.902.

Application filed November 9, 1,399. Serial No. 736,424. (No model.)

.To ct whom, t may concerns Be it known that I, BERNHARD Kissen, asubject of the Emperor of Austria-Hungary, residing at Vienna, in theProvince of Lower Austria, in the Empire of Austria-Hungary, haveinvented certain new`and useful Improvements in Braiding-Machines; and Ido hereby declare the following tobe a full, clear, and exactdescription of theinvention, such as willenable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters and figures of referencemarked thereon, which form a part of this speciiication.

A machine according to this invention is specially adapted for coveringropes, cords, 'or cables with braid to form an outer covering therefor.Such a braiding-machine differs from the hitherto usual verticalbraiding-machines by having a horizontal axis and is characterized bythe fact that the bobbins corresponding to one group of braiding-stripsare moved alternately to and fro on the spindles (which are locatedvopposite ,to one another) of two disks or spiders (hereinafter calledspiders) which rotate in the same direction and at the same speed, sothat the said bobbins travel along a wavy line on the cylindricalsurface described byv the spindles, While the other group ofbraiding-strips rotates between and in direction opposite to that of thetwo spiders, so that from the two groups of threads of thebraiding-strips there is formed a braid that surrounds the rope orcable, which moves continuously through the hollow pivots of thespidersand a central bush. Each braiding-strip consists cfa number ofyarn-threads which must lie parallel braiding-strips whose bobbins arealternately moved over from the spindles of one spider to those of theother and which therefore travel in a wavy path these thread-guidesconsist of inwardly-opening forks which have a notch for each thread.These forks are located opposite toone another at a certain distanceapart, so that the threads of the braiding-strips rotating in thecentral plane can pass between them, and they approach each other onlyfora short time during the transfer of the bobbins for the purpose ofinsuring the transfer of the braiding-strips from the right-hand forkslto the left-hand forks, or vice versa. The transfer of the bobbins fromone spider to the opposite one is caused byV oscillating levers, and thebobbins are held in their position for the time being against the pullof the braiding-strips by spring-pawls, which are released as soon asthe levers are set in motion. The accompanying drawings illustrate anexample of such a braiding-machine in which eight braidingstrips areused.

Figure l shows a vertical section of the machine, symmetrical portionsbeing shown only once and the horizontally-arranged transmission-shaftsappearing turned up into the vertical plane. Fig. 2 is a sectional sideelevation of the braiding-machine, in which for the sake of clearnesscertain parts are omitted. Fig. 3 is a development of thebraiding-paths.

Fig. 4 shows analogously the curved grooves that operate the levers.Fig. 5 is a side View, and Fig. 6 a plan, of a thread-guide. Fig. '7 isan inside view of the arrangement of the thread-guides relative-to thebush. Fig. 8 is a development ofthe curved grooves by means of which theth read-guides are actuated. Fig. 9 is aside elevation, and Fig. lO across-section, of the braided rope or cable.

, The parts d andkb are two rigidly-fixed heads, which are locatedopposite to each other and are turned cylindrical at their inner endsand which form the pivots for the rotating spiders c. One head a has atits inner end a cavity for the bush d, which serves to compress thebraiding, while both heads are bored out for the passage of the rope orcable c. The spiders c, each of which carries `four spindles f .ofsquare cross-section, are rotated at the same speed and in the sainedirection by means of bevel-wheels g, which are mounted on their hubsand which engage the bevel-wheels h of ICO vthe corresponding shaft 'L'.

the shafts i, so that the `spindlesfof the one spider are always locatedopposite to those of the otherspider. The four bobbinsj, on which thethreads of the braiding-strips lc of the one group are Wound, cantherefore be moved during their rotation around the axis of the machinefrom the right-hand spindlesf to the left-hand ones, and vice versa.Each bobbin j is rotatably mounted on a sleeve Z, which lits the squarespindle fand is rigidly fixed to a frame fm, that carries a tensiondevice. (Not shown in the drawings.) The bobbins 'j are moved fromspindle to spindle by singlearm levers n, which are pivoted at o on thehubs of the spiders c and embrace the spindlesfwith their forked endsand which are oscillated by means of sliding rods p, that engage thecurved grooves of disks q. Each disk q is loosely mounted on the hub ofthe corresponding-spider c and is driven at the same speed as thespiders c, but in the direction opposite to that of the spiders, by abevelwheel r of a hollow shaft s, that surrounds On each of the disks qthere are fixed four arms on which are mounted spindles o, which arecircular in cross-section and are adapted to carry the bobbins tt, thatcontain the yarn-threads that form the four braiding-strips w of thesecond group. In the present case the yarn of each braiding-strip w isdistributed on two bobbins u, which can therefore be much smaller thanthe bobbinsj, while containing the same length of yarn. From the bobbinsu the yarn passes over the ends (which are bent inwardly and screwedtogether) of the arms t and join together to form a braiding-strip w ineach of the four radial sheath-like thread-guides which are attached tothe arms Zand carry at their inner ends perforated thread-guide platesfy. The lthreads of the braiding-strips 7c, proceeding from the bobbinsj, are led near to the bush CZ through thread guide forks Z, Figs. 5 and6, which are turned with their openings inward-71. e., the openings ornotches of each fork Z are turned toward those of the fork Z opposite toit. These forks are mounted on stems 3,which carry square bosses 2 andare horizontally movable in supports 4E, fixed to the spiders c, whileby their inwardlybentinner ends they engage in curved grooves 5 ofrings, which are fixed rigidly to the heads a and b, respectively.

In order to prevent the bobbinsj from being drawn inward by the tensionof the braiding-strips Zt proceeding toward the bush d, there is mountedon each lever n a springpawl 7, which as soon as the bobbin arrives fromthe opposite side snaps in behind the projection 8 of the bobbin-framem,and thereby holds the bobbin fast. This pawl is disengaged when thelever 'n begins to push the bobbinj inward.

The driving of the machine is effected by the main driving-shafting 9,which carries at each end-a bevel-Wheel lO, that forms a reversingmotion in combination with a bevelwheel 11, fixed on the shaft t, and abevelwheel 12, keyed on the hollow shaft s. The shafts i and s thereforerotate in opposite directions, but at the same speed.

For the purpose of facilitating the changing of the bobbins j thebevel-wheels 7L are held in position to gear with their respective gearsg by a sleevesecured to its shaft t' by a lock-screw, Fig. l, so that byloosening the latter the said bevel-gear h can be` moved along the shaftout of gear with g, thus permitting the rotation of one spider cindependently of the other.

When working, the bobbins j are carried in a circle around the rope e tobe braided and are at the same time pushed across by the levers nalternately toward the one side and the other. The braiding-strips Zt,which must follow the movement of the bobbins, travel along the wavyline shown in Fig. 3, while the braiding-strips 'w move continuously inthe central plane of the machine. In this manner there is formed in thepresent case an eight-stranded braid in which each strip of the onegroup crosses each strip of the second group.

Figtisadevelopment of the curved grooves which are arranged in the diskq and which set theleversnin motion by means of the sliding rods p. Ineach disk there are two sliding rods which are located on linesradiating at an angle of one hundred and eighty degrees from each otherand engage in the groove indicated by full lines, which is arranged inthe flange of the disk itself, and also two other IOO sliding rods,which are likewise located on lines radiating at an angle of one hundredand eighty degrees from each other, but engage in the groove indicatedby broken lines,

which is located on the inner surface of a bi partite ring 14, screwedto the disk. Each lever 'n pushes the bobbing', located in front of it,upon the spindle fof the opposite spider c and thereupon returns at onceto its normal position, so that it avoids the thread-guide sheaths x,which pass between the ends of the spindles f. The perforatedthread-guide plates y hold the several threads of the strips zu besideone another, and the threads of each braiding-strip 7c are led throughthe notches of the thread-guide forks Z, which follow the movement ofthe braiding-strips.

In Fig. 8 there is showna development of the curved grooves 5 of theabutment-collars 6, in which the outer ends of the fork-stems 3 engage.As soon as a bobbin j is pushed over the fork Z, guiding thecorresponding braiding-strip Zt, and the fork located opposite to itmove inwardly toward each other, so that these forks almost touch whilethe threads are being transferred from the one fork into the other.Thereupon the two forks separate again in order to provide room for thepassage of the braiding-strip w, so that while the one fork is empty theother holds the braiding-strip, which by reason of its tension liesclose in the notches of the fork.
